This is one hobby my wife has had no problem with at all and even encourages me:-) If I find a razor that is very attractive she wants to see the picture and actually appreciates them.
I get a Caswell & Massey catalog and while I don't buy much from them she has discovered it and orders ladies products from it. I even got her to try a DE and now she's a convert to those and swipes my mint shave cream from time to time--LOL!
